More Maths resources may be found on the Galileo Educational Network website, which is the professional learning arm of the Werklund School of Education at the University of Calgary.

See Designing Learning, and in particular Designing For Deep Mathematical Understanding and Math Fair Problems.

There are also a number of relevant Classroom Examples and some Math Investigations.

I don’t know how useful these resources are for Maths, but I flag them because there are some very helpful articles on inquiry, especially What is Inquiry?, which addresses some of the misconceptions about inquiry. There is also the excellent Focus on Inquiry (see below).
